The SI unit of force is the newton , symbolized as N. One newton is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared. In terms of SI base units, this is expressed as:

1 N=1 kg⋅m/s21\text{ N}=1\text{ kg}\cdot \text{m/s}^21 N=1 kg⋅m/s2

This unit is named after Sir Isaac Newton in recognition of his work on classical mechanics and his second law of motion, which states that force equals mass times acceleration (F=maF=maF=ma)
